Wow, that's a lot of info, thunderblade, and that's exactly what I would like to happen in the future after the Sinnoh Leauge.
I'm gonna try out five episodes that'll probably take place in Sunyshore City. (Sorry if they're long; got carried away a bit)
DP148- Bright Sunny Days! Arrive in SunnyShore!!:
When the gang has finally reached Sunnyshore, they are encountered by Elite Four Flint! Along with his Infernape, he's looking for someone to help regain Volkner's confidence. On their way to the Beacon tower, they are greeted by Jasmine and her Magnemite. As Ash and Brock are familiar with her. All of them head for the tower to confront Volker. Once there, Ash asks why he is not at the Gym. Apparently, after a huge defeat between Paul, previously, he got depressed that Paul had only need for getting the Beacon Badge. Volkner was unable to defeat any of his Pokemon, as Paul's Electabuzz had defeated all of Volkner's Electric types. Jasmine offers to have a battle with him, since they come from a similar issue, and both of their cities are alike. He agrees, and they both have a battle in the next episode.
DP149- Two Bright Sides! Volkner VS Jasmine!!:
In this episode, Volkner and Jasmine have their battle at the Gym. They have a 4-on-4 battle. Volkner uses Raichu, Luxray, Jolteon, and Electivire. Jasmine uses Magnemite, Steelix, Togetic (newly caught), and Magnezone. Volkner ends up winning with 2 Pokemon still active, and Jasmine goes down with her last Pokemon, Magnezone. Then, Volkner is still depressed, because he won a bit easily. Though, he tells Ash they'll have a battle later. Once the 5 (Ash, Dawn, Brock, Jasmine, and Volkner) leave the Gym, Volkner has a small grin on his face to show he has something up his sleeve.
DP150- Shocking Battles! Ash VS Volkner!!:
In this episode, Ash finally gets his battle with Volkner. In this episode, Volkner chooses the same Pokemon from the previous episode. Ash uses Pikachu, Gliscor, Monferno, and Grotle. Close to the end, Ash is left with only Gliscor and Pikachu. Volkner remains with only Luxray and Electivire. Gliscor goes against Luxray, and they end up in a big draw. Both are called back, and it's now Pikachu vs Electivire. From Volkner's grin seen in a flash back, he reveals to Ash that this is no ordinary Electivire. (From the previous episode, only 2 moves were used against Jasmine). From the start, Volkner begins using Ice Punch constantly on Pikachu. Pikachu comebacks with Volt Tackles and Iron Tales. Then, Electivire is unleashing a big move...Earth Power. Pikachu is unevengly match, but his final Volt Tackle in battle turns the tables. Once he uses Volt Tackle, it spreads across the battle field. It super effects Electivire with Thunder and Ground moves against him. He goes down, and Ash wins the Beacon Badge. Therefore, Volkner regained his real confidence again, and is pleased from the battle. Once they gang leaves, Flint returns to the Elite Four, after telling Ash about more of the Elite Four challenge. Jasmine decides to compete in the next contest that takes place in Sunyshore. Dawn also competes in it to win her 5th and final ribbon.
DP151- Pokemon Contest! Sunnyshore Convention!!:
In this episode, Dawn is psyched for her contest, along with Jasmine, whom has revealed she had never tried out a contest ever. Dawn gives her some encouragement, and Jasmine gets excited as well. Once things go amazing for Dawn, she's not too happy to see an old friend who's competing...Urara. Apparently, she's still mad she lost the Akebi contest, and wants to make up for it by winning this contest. During the contest, Dawn, Jasmine, Jessie, and Urara have all made it to the 1st round. In the 2nd round, Dawn, Jasmine, and Urara make it. With Jessie being defeated by Urara with her Gabite. In the next round, Jasmine suprisingly defeats Urara, and Dawn makes it to the next round, too. In the final round, Dawn goes against Jasmine. It's Mamoswine against Magnezone. Dawn ends up winning her 5th ribbon for the Grand Festival. And now she can enter it. Also, at the end, Mamoswine comes out of the PokeBall, and shows that he/she has finally befriended Dawn. (awww)
DP152- Beacon Trouble!! Stop Team Rocket!!:
In the final episode to take place in Sunyshore City, Team Rocket has taken control of the Beacon tower to possess all of it's energy for Team Rocket. The 4 confront Team Rocket, and their amazingly strong. To stop them, they are greeted by this older guy with strange gray/light blue hair. He sends out his Gallade and is able to help try to defeat Team Rocket. But once they succeed, the city's light goes out, and the whole city is darkened. So the 5 head for the electricity control room to heal this problem. Though it's hard to located once all of the electricity is gone. Can they find it and save Sunyshore?
